About Sylvan Springs

Sylvan Springs bubbles with intense geothermal energy in Yellowstone’s Gibbon Geyser Basin, offering a raw and immersive hot spring experience. Its collection of steaming pools buzzes with natural power, immersing you in a wild landscape shaped by underground heat. This primitive hot spring stands out among Wyoming swimming holes for those craving rugged adventure.

Getting There

Reaching Sylvan Springs demands a challenging trek across open terrain along the south edge of Gibbon Meadows, taking over an hour on rough, unmarked paths. Parking near the basin is very limited, so plan accordingly and prepare for a strenuous hike with no formal trail.

What to Expect

Expect water temperatures soaring around 192°F, intense enough to test your limits and require caution. The area feels remote and untouched, with minimal visitor presence and no built amenities, allowing you to soak in solitude amidst Yellowstone’s geothermal symphony.

Tips for Visitors

Bring sturdy footwear, plenty of water, and navigation tools for the cross-country hike since trails aren’t maintained. Avoid visiting alone and shade the hottest pools with care to prevent burns. There’s no guaranteed parking or fees posted, so arrive early and pack out everything you bring in to preserve this wild Wyoming hot spring.
